Hi Kyle Thank you for your inquiry. Regarding the bands in Rever, each section are made of many independent fibers(each band) which makes it impossible to break all of them at the same time. Therefore, there is no need to worry about this. The pulleys are made of aluminum 7075 with a titanium bar that goes side to side. Also imposible to brakes.
The rubbers are of standard sizes, which means that you can order them from us as well as from other platforms such as eBay or Amazon. This ensures that you do not depend solely on us if we do not produce the bands in 10, 20 years or more. The mechanics of the product are super simple, so you do not need to ship the arm for maintenance.
Furthermore, the bands are quiet and t
he elasticity of the rubber is what creates an amazing boom range using just your fingertips.
And the only thing you have to do is add more rubber bands if you add weight or remove if you go lighter.
We hope this information helps! Let us know if you have any further questions or concerns.
